Large size provides a wide area of coverage from low mounting heights. Will accommodate all sizes of MH and HPS lamps. Low mounting height reduces distance to plants and thus increased light levels.
Reflector dimensions: 48 in Diameter x 10 in Deep. It operates MH and HPS lamps in the horizontal position but in an eight-sided parabolic shaped reflector. In the horizontal burning position, much of the lamp's light is thrown straight down and the balance of the lamp's light which is emanating upward is re-directed back down to the plant canopy from the 95% reflective German aluminum insert. Pre-wired with lamp cord and adjustable socket. Does not accept BT56 lamps.
Galaxy Legacy Select-a-Watt 400/600/Turbo Charge Electronic Ballast - 120/240 Volt
Pre-programmed with a digital random start feature. It will delay 1-3 seconds each time it starts. Reduces in-rush current spikes when starting multiple ballasts at a time. These state-of-the-art ballasts are manufactured to provide today's serious grower with maximum flexibility & performance. The Galaxy Legacy is different than any other dimmable electronic ballast on the market. Lamps are only dimmable on wattages lower than the specified lamp wattage. A 1000 watt lamp can be dimmed down to 600 or 400 watt. A 600 watt lamp can be dimmed down to 400 watt but cannot be over-driven to 1000 watts.
On this unit Turbo Charge is designed for 600 watt lamps only. There are three ways to use the Select-A-Watt feature: It will properly drive a 400, 600 or 1000 watt lamp to ANSI specifications. For example: Set the switch to 400 watts, insert a 400 watt lamp into your socket and the ballast will operate the 400 watt lamp. The ballast will similarly operate 600 watt lamps. The second option is to dim a 600 watt lamp. Adjust the switch to 400 watts and the ballast will dim the 600 watt lamp. The Turbo Charge feature will increase the output of a 600 watt lamp by approximately 10%. Purchase a 240 volt power cord separately.
